Operation
Connection diagram for dual voltage, single-phase motors. Your dual-
voltage motor's terminal board (under the motor end cover) will match one
of the diagrams below. Follow that diagram if necesary to convert motor to
115 Volt power.
Connect power supply wires to L1 and L2. For 3-phase motors, or if motor
does not match these pictures, follow the connection diagram on the motor
nameplate.
Hazardous voltage. Can shock, burn, or cause death.
Disconnect power to motor before working on pump or motor. Ground
motor before con necting to power supply.
THE MOTOR IS SET FOR
230 VOLTS WHEN SHIPPED.
To change the motor to use 115 volts:
1. Turn off power
2. Remove the back motor cover.
3. Use a screwdriver or 1/2" wrench and turn the voltage selector dial
counterclockwise until 115 shows in the dial opening.
4. Reinstall the motor cover.
WIRING
Ground motor before connecting to electrical power supply. Failure to
ground motor can cause severe or fatal electrical shock hazard.
Do not ground to a gas supply line.
To avoid dangerous or fatal electrical shock, turn OFF power to motor
before working on electrical connections.
Supply voltage must be within ±10% of nameplate voltage. Incorrect
voltage can cause fire or damage motor and voids warranty. If in doubt
consult a licensed electrician.
Use wire size specified in Wiring Chart (Page 8). If possible, connect
pump to a separate branch circuit with no other appliances on it.
Wire motor according to diagram on motor nameplate. If nameplate
diagram differs from diagrams above, follow nameplate diagram.
